I just realized that this hunk does not belong to the patch. Please
ignore it when reviewing.
Looking at this patch again made me think...
Libvirt is a connection based (ie. client / server) system. Which
means that basically *any* function could fail -- except those which
don't require a valid connection.
Self-NACK in this case.
This is a bit misleading in the documentation; I would have assumed
that a function documented as returning NULL representing "nothing
found" has no other meaning of indicating an error. But, rather, it
means either nothing found or an error occurred and I have to check
for an error, right?
